Decoding

import sbe

with open('your-schema.xml', 'r') as f:
  schema = sbe.Schema.parse(f)

wtih open('your-data.sbe', 'rb') as f:
  buf = f.read()

# Get a Python dict in one-line
x = schema.decode(buf)

x.name  # The template message name
# 'PriceFeed'

x.value
# {'userId': 11,
# 'timestamp': 1598784004840,
# 'orderSize': 0,
# 'price': 5678.0,
# ...

# If you need an offset, apply them Pythonicaly
schema.decode(buf[19:])

# decode_header to avoid filter out messages based on header to avoid decoding
# message bodies that are not needed
schema.decode_header(buf)['templateId']

Encoding

import sbe

with open('./your-schema.xml', 'r') as f:
  schema = sbe.Schema.parse(f)

# message_id from the schema you want to encode
message_id = 3

# Encode from Python dict in one-line
schema.encode(schema.messages[3], obj)

# You can supply your header values as a dict
schema.encode(schema.messages[3], obj, headers)
